My period has been regular and on time every month like clockwork. I'm 2 days late right now and should have started my period on Friday. I'm not sure what's going on. It's starting to stress me out. There's no way that I'm pregnant. I haven't had a late period since finding out I was pregnant with my now 15 month old. I had a bad migraine that lasted 4 days from Sunday- Thursday and I took Tylenol twice a day during 3 of those days. I'm wondering if taking the Tylenol or something could have caused me to be late and mess up my cycle? Also me and my mom got into a heated crying argument on Sunday which lead to causing the migraine. I just hope my periods aren't getting messed up because of this. I'd like to atleast have one more baby sometime since the doctor said my uterus looks good to try for one more baby. I have two kids right now and they were both c sections. My 2 and a half year old I had to go to a fertility specialist to get pregnant with her. My periods were irregular and found out one of my tubes were blocked so I got them unblocked and took Femara and got pregnant with her. Ever since having her my body went back to normal and ive had regular periods ever since. I also conceived my second child naturally which is amazing. I'm just scared of my body going out of whack like it was before my first baby. It was a very hard time
